BACKGROUND

The technical field is antiballistic materials and armored panelsconstructed therefrom. The technical field also includes constructiontechniques incorporating armored panels in vehicles and otherstructures.

Many forms of antiballistic materials and barriers are available. Suchmaterials are classified according to their ability to deter ballisticattacks. Underwriters Laboratories (UL) Standard for Safety forBullet-Resisting Equipment (i.e., UL-752 requirements) covers materials,devices, and fixtures used to form bullet-resisting barriers thatprotect against robbery or holdup. The term “bullet-resisting” generallysignifies that protection is provided against complete penetration,passage of fragments of projectiles, or spalling (i.e., fragmentation ofthe protective material) to the degree that injury would be caused to aperson standing directly behind the bullet-resisting barrier.

The UL-752 requirements are classified according to levels, beginning atLevel 1. Higher UL levels provide greater protection againstprojectiles. However, greater protection against ballistic attacktypically requires heavier and larger ballistic materials. When theobject to be protected is a building, the total weight of anyantiballistic shielding is limited by the ability of the building tosupport the additional weight of the shielding. For example,conventional shielding for buildings and other structures involvesadding concrete or steel layers to the building walls. These layers ofshielding material add considerable weight to buildings and otherstructures. In particular, due to this added weight, conventionalshielding materials may not be suitable for taller buildings and otherstructures. Additionally, conventional shielding materials, such assteel, are costly. Moreover, mobile objects requiring antiballisticshielding are similarly subject to the same or even more stringentweight and cost limitations.

The inner matrix or armored wall panel may be added to existingobjects, structures and vehicles, or the armored wall panel can be usedin the construction of new objects, structures and vehicles.

The present invention is directed to an antiballistic armor matrix ratedat up to UL level 8. In particular, the present invention is directed toa special orientation of composite lightweight building materials thatcreate a resistant barrier against many destructive forces, natural andmanmade, without the use of reinforced concrete or ballistic steel. Thepresent invention is designed and tested to contain a multiple shotassault from high-powered FMJ (Full metal jacket) ballistic projectiles,while maintaining a maximum UL Level 8 (i.e., an UnderwritersLaboratories testing criteria). The present invention is preferablycomprised of one or more of the following materials: fire-rated gypsumboard, structural pre-insulated light gauge steel panels/components,commercial grade adhesives or tape, cementeous board, commercial gradequarry tiles, tempest mesh Aramid-Fiber sheets and/or KEVLAR®. In otherembodiments the present invention is directed to two or more of theabove materials in any combination. The present invention is furtherdirected to methods for forming/making and installing such materials.

FIG. 1 to FIG. 4 illustrates one embodiment of the present invention.FIG. 1 is an end view of a portion of an interior antiballistic armoredwall panel assembly 200. FIG. 1 shows a configuration comprising: aplurality of tracks 203, a first panel 205, a first set of Aramid-Fibersheets 207A, a second set of Aramid-Fiber sheets 207B, a first backerboard 209, a layer of tiles 211 and a second backer board 213. Inaddition, an interior surface 201 and a plurality of lips 225 (notshown) precedes the first panel 205.

FIG. 2 illustrates an exploded perspective view of the interiorantiballistic armored well panel assembly 200. FIG. 2 shows aconfiguration comprising: an interior surface 201, a plurality of lips225, a plurality of tracks 203, a first panel 205, a first set ofAramid-Fiber sheets 207A, a second set of Aramid-Fiber sheets 207B, afirst backer board 209, a layer of tiles 211 and a second backer board213.

FIG. 3 illustrates a fragmental cross-sectional view of the interiorantiballistic armored wall panel assembly 200. FIG. 3 shows aconfiguration comprising: an interior surface 201, a plurality of tracks203, a first panel 205, a first set of Aramid-Fiber sheets 207A, asecond set of Aramid-Fiber sheets 207B, a first backer board 209, alayer of tiles 211 and a second backer board 213. In addition, FIG. 3clearly illustrates the inner matrix comprising: the first set ofAramid-Fiber sheets 207A, the second set of Aramid-Fiber sheets 207B,the first backer board 209, the layer of tiles 211 and the second backerboard 213.

The interior surface 201 may be, for example, fire-rated gypsum board ordrywall as is known in the construction industry. The interior surface201 is used as a facing material when the interior antiballistic armoredpanel 200 is used in residential, commercial and other constructionenvironments.

The plurality of tracks 203 are used to contain and solidify theantiballistic armored panel assembly and provide structural integrity.As a non-limiting example, the plurality of tracks 203 can be made fromsheet metal. Other materials, such as galvanized steel and mild steel,can also be used to form the plurality of tracks 203. The plurality oftracks 203 may have a non-limiting height of 3″ and a width of 10″. Theplurality of tracks 203 can be attached to the first panel 205 using,for example, self-tapping drill tip screws, equivalent fasteners orwelding.

The first panel 205 may be made, for example, from metals such as lightgauge steel. A non-limiting example of such a light gauge steel isTHERMASTEEL®, which is manufactured by THERMASTEEL Corp., Radford Va.

The first panel 205 may have varying thicknesses depending upon thedesired application. As a non-limiting example, the first panel 205 mayhave a thickness in the range of about 3½″-7½″. The first panel 205provides a structural, sound-diminishing, insulated, and lightweightcarrier for the inner matrix discussed above.

In addition, the first panel 205 may be insulated. Insulation in thepolystyrene steel panel 205 may have the form of a rigid, fire-retardantmodified expanded polystyrene resin (EPS) bonded to the steel.

The first panel 205 may be used as load-bearing portions of a steelframe structure. Therefore, the interior antiballistic armored panel 200can be used as a load-bearing element in roofs, floors, and walls.

The first set of Aramid-Fiber sheets 207A and second set of Aramid-Fibersheets 207B can be a layer of high strength ballistic fiber material. Anon-limiting example of such a ballistic fiber material is KEVLAR®.KEVLAR® consists of long molecular chains produced frompoly-paraphenylene terephthalamide. KEVLAR® is a polyamide, in which allthe amide groups are separated by para-phenylene groups. That is, theamide groups attach to the phenyl rings opposite to each other, atcarbons 1 and 4. KEVLAR® is five times stronger than steel, weight forweight. KEVLAR® provides excellent impact resistance and is one of thelightest structural fibers available. KEVLAR® is generally yellow incolor and soft to touch. KEVLAR® 29 is used for ballistic protection.KEVLAR® is available from E. I. du Pont de Nemours and Company.

The first set of Aramid-Fiber sheets 207A and second set of Aramid-Fibersheets 207B can act as spalling liners and therefore provides projectilecontainment layers. KEVLAR® fibers can be woven into sheets that can becompiled by layering the sheets to the desired number necessary for theprotection level necessary (e.g., 4 layer; 9 layer, etc.). In onenon-limiting example, first set of Aramid-Fiber sheets 207A and secondset of Aramid-Fiber sheets 207B are about ¼″ thick.

Alternative materials for the first set of Aramid-Fiber sheets 207A andsecond set of Aramid-Fiber sheets 207B include the following:

TWARON® is another aramid flexible ballistic laminate material suitablefor use in the present embodiments. TWARON® is a lightweight, highstrength fiber made from aramid polymer supplied by Accordis. TWARON's®characteristics include good dimensional stability and high modulus.

SPECTRA® is an ultra lightweight, high-strength polyethylene flexibleballistic laminate fiber material developed by Honeywell InternationalCorporation. SPECTRA® has high damage tolerance, non-conductivity,flexibility, high specific modulus and high energy-to-break, lowmoisture sensitivity, and good UV resistance. SPECTRA® is typically usedin ballistic and high impact composite applications.

ZYLON® is another flexible ballistic material. ZYLON® consists of arigid chain of molecules of poly (p-phenylene-2, 6-benzobisoxazole)(PBO). ZYLON® is available from Toyobo and has excellent tensilestrength and modulus properties.

In another non-limiting example, the layers 207A, 207B may beconstructed of steel plates. The layers 207A, 207B may be attached, forexample, by polyurethane adhesive as discussed above. If steel platesare used, the layers 207A, 207B may have a thickness in the range ofabout ⅛″-¾″. A non-limiting example of steel plates may be mild coldrolled steel plates.

The first backer board 209 and second backer board 213 may be, forexample, cementous boards. Moreover, fire-proof cementous backer boardsare preferably used because the interior antiballistic armored panel 200may be used in office buildings or other inhabited structures. The firstbacker board 209 and second backer board 213 may have a thickness in therange of about ¼″-½″. In one non-limiting example, the first backerboard 209 and second backer board 213 are about ¼″ thick. In anothernon-limiting example, the first backer board 209 and second backer board213 are 5/16″ thick. The first backer board 209 and second backer board213 serve as containment layers. A non-limiting example of a backerboard is sold under the trade name HARDIBACKER® manufactured by James A.Hardie Siding Products, located in Mission Viejo, Calif.

The layer of tiles 211 may be made from individual tiles. In onenon-limiting example, the layer of tiles 211 is made from a ceramic tilesuch as a quarry tile. Alternative tiles, such as paver tile andequivalents, may also be used. The layer of tiles 211 may have athickness in the range of about ¼″-½″. In one non-limiting example, thelayer of tiles 211 is about ½″ thick.

The layer of tiles 211 can be constructed from a variety of sizes oftiles such as, for example, at least 6″×6″ tiles. The layer of tiles 211may be formed by being set in an adhesive. As a non-limiting example,the adhesive can be at least one of polyurethane and urethane tileadhesive.

Properties of a non-limiting example of quarry tile suitable for formingthe layer of tiles 211 are summarized in Table 1.

TABLE 1 Quarry Tile Specifications Test Results ASTM# Result BreakingStrength C648 >350 lbs Scratch Hardness MOH's 7 Chemical Resistance C650Resistant Coefficient of Friction C1028 Wet ≧ 0.60 Dry ≧ 0.80

Alternatively, the layer of tiles may 211 may be formed from at leastone of commercial grade quarry tiles and ceramic tiles set in a urethaneadhesive as used in commercial construction. The urethane adhesive canserve as a bonding agent for the elements of the inner matrix.Non-limiting examples of suitable urethane adhesives for the layer offiles 211 are sold by Bostik Findley under the trade name CHEM-CALK.

Moreover, adhesives are used to attach/cement adjacent layers of theinterior antiballistic armored panel 200. The adhesives used toattach/cement the adjacent layers may be industrial grade adhesives usedin the field of commercial construction. Non-limiting examples of suchadhesives include polyurethane and urethane. An example of apolyurethane construction adhesive is sold under the trade namePL-BRANDS by OSI Sealants, Inc., of Mentor Ohio.

In addition, tape may be used to attach the adjacent layers of theinterior antiballistic armored panel 200. The tapes used to attach theadjacent layers may be industrial grade tapes used in the field ofcommercial construction. A non-limiting examples of such tapes includedouble-stick tapes, double coated acrylic foam tapes and adhesivetransfer tapes. A non-limiting example of a double-stick tape is soldunder the trade name VHB® by 3M®, of Minneapolis, Minn.

A metallic mesh (not shown) can be include in the interior antiballisticarmored wall to prevent eavesdropping of electromagnetic emissions fromdata processing and related equipment may be included in the interiorantiballistic armored panel 200. A non-limiting example of such ametallic mesh is TEMPEST© mesh, a fine woven copper wire fabric. Themetallic mesh would be grounded to provide a shielded environment. Themetallic mesh can be installed between the first panel 205 and first setof Aramid-Fiber sheets 207A or between the second set of Aramid-Fibersheets 207B and the first backer board 209. The metallic mesh can beattached to either the first set of Aramid-Fiber sheets 207A or secondset of Aramid-Fiber sheets 207B by either manual screws or equivalentfasteners or an adhesive fastening system. Alternatively, the metallicmesh may be installed between other layers of the antiballistic armoredpanel based on ease of construction, etc. The metallic mesh may be usedfor highly sensitive soundproof structures or areas within a structureand distorts and/or minimizes the effectiveness of listening devices. Itis well known in the art of TEMPEST systems that grounding such ametallic mesh can provide shielding of electromagnetic signals.

The antiballistic armored panel assemblies 200 can be used as aload-bearing element in roofs, floors, and walls. Combinations of panelassemblies 200 may be screwed together to form a strong, lightweightbuilding structure.

Example 1

The following example illustrates test results for one embodiment of thepresent invention conducted by Underwriters Laboratories Inc.

Two test panels of bullet resisting wall material rated for UL Level 8and designated “Ballistic Armor Matrix (BAM)-8” was submitted fortesting. The construction of the wall material was as follows:

⅝″ gypsum board;

3½″ THERMASTEEL® panel;

¼″ cementous fiber board;

½″ quarry tile;

¼″ cementous fiber board;

9 layer rigid KEVLAR®, two panels overlapping (i.e., a total of 18layers);

3½″ THERMASTEEL® panel; and

⅝″ gypsum board.

The ammunition used for the investigation was 150 grain (9.7 g) 7.62 mmrifle lead core full metal copper jacket, military ball, minimumvelocity 2750 fps (838 mps). All tests were conducted at close range,approximately 15 ft (4.6 m), using the ammunition and weapon specified.The test samples were mounted, with ⅛″ (3.2 mm) thick corrugatedcardboard indicator panels placed approximately 18″ (467 mm) behind theprotected side of each test sample. During the test, each bulletvelocity was monitored and recorded.

The sample was subjected to a 5-shot test. The 5-shot test consists offive shots placed in a square pattern that is 4½″ by 4½″ (114 mm)located in the center of the test sample. With this shot pattern, thereshall be no penetration of the projectile through the test sample, norspalling of the material on the protected side of the test sample, tothe extent that fragments embed in or damage the cardboard indicators.The velocity of each bullet was recorded during the test.

Test panel number 1 was constructed as a central wall panel such that noseams in the KEVLAR® panels were provided in the UL Level 8 test patternarea. 5 shots were placed for the UL Level 8 rating in the approximatecenter of the test sample. Following the five shots, there was nopenetration of the projectiles, nor spalling of material on theprotected side of the test sample. Results of this test are acceptablefor the UL Level 8 rating in accordance with UL 752.

Test panel number 2 was constructed as a panel with a seam at the centersuch that seams in the KEVLAR® panels were provided in the UL Level 8test pattern area. That is, in such a manner that the first four shotsof the pattern would impact on the seams. Five shots were placed as forthe UL Level 8 rating in the approximate center of the test sample.Following the five shots, there was no penetration of the projectiles,nor spalling of material on the protected side of the test sample.Results of his test are acceptable for the UL Level 8 rating inaccordance with UL 752. The results of both tests discussed above aresummarized in Table 2 below.

Example 4

FIG. 13A to FIG. 13N illustrates an exemplary apparatus and method formaking and installing a reinforced structure 1300 formed from armoredpanel wall sections or panel assemblies such as 200, 600, 900. Theassemblies include armored panels such as 200, 600, 900 and additionalcomponents. The finished structure 1300 is illustrated in FIG. 13N.

EXAMPLE 4 describes in detail the assembly of oneantiballistic/anti-forced entry interior or exterior armored panel/wall.The reinforced structure 1300 can serve as either structuralload-bearing device used to form a structure such as a building, or asreinforcement to an existing structure such as a wall, room, building orvehicle.

In EXAMPLE 4, assemblage of the reinforced structure 1300 is describedas a process for forming a new structure in which the reinforcedstructure 1300 serves as a load-bearing element. In this embodiment, theassemblies 200, 600, 900 can be used as an alternative to, for example,concrete slabs.

FIG. 13A is perspective view of track 1303 being installed on a floor.In FIG. 13A, a bent L-shaped, 10 gauge track 1303 is mounted to thefloor and ceiling (e.g., an in-fill panel). The plurality of tracks 1303may have a non-limiting height of 3″ and a width of 10″. The pluralityof tracks 1303 may be placed on the floor and ceiling approximately 10″from the exterior face of the concrete. The plurality of tracks 1303 maybe installed using ½″×1″-3″ anchor bolts mounted in the floor andceiling, spaced 1 meter on center (O.C.), and the pattern of theplurality of tracks 1303 may be laid out in a desired pattern beforemounting the assemblies 200, 600, 900, as shown in FIG. 2, FIG. 6 andFIG. 10, respectively. Alternatively, each of the plurality of tracks1303 can be bolted to the ceiling and/or floor as assemblies 200, 600,900 are constructed.

Referring to FIG. 13B, after the plurality of tracks 1303 are installed,a first panel 1305 is mounted in the plurality of tracks 1303. The firstpanel 1305 may have a floor to ceiling clearance of about ¼″. Theinterior surface 1301 for the reinforced structure 1300 is whereelectrical outlets may be installed and on which a finished wall surfacemay be applied. The interior side of the first panel 1303 is attachedtop and bottom on the vertically extending lip of the track 1303. A lip1325 is attached to the track 1303 by welds 1304. A plurality of lips1325 is used to hold the armored panel. The lip may be about 3″ inheight, and ⅞″ self-tapping metal screws can be used to attach the firstpanel 1305 to the lip 1325. In addition screws on the top and bottom canbe spaced approximately 6″ apart (e.g., 3 screws per stud at the top andbottom or welding studs at the top and bottom).

First panel 1305 are attached in this manner until the entire outline ofthe reinforced structure 1300 is covered with framing panels 190.Attachment plates (not shown) are used to attach adjacent panels. In oneembodiment, the attachment plates are at least 3″×6″, 18 gauge metalplates. Four screws may be used to attach each side of a plate a firstpanel 1305. The first panel 1305 can include steel studs for receivingthe screws. The steel studs can be 3½′ wide galvanized steel studs. Theoutside of the first panel 1305 has a leading edge which is an 18 gauge3½″ overlap which can be attached with ⅞″ self-tapping screws every 6″.

Referring to FIGS. 13C-13D, once the first panel 1305 is secured, alayer of adhesive is applied to the first panel 1305. A panel seam isshown at 1306. The adhesive or tape may be applied, for example, using a⅛″ notched trowel. Once the adhesive or double-stick tape is applied, afirst layer of the first set of Aramid-Fiber sheets 1307A is applied tothe adhesive. The first set of Aramid-Fiber sheets 1307A and adhesive ordouble-stick tape are applied in conjunction with one another to preventthe adhesive from drying during assembly. The first set of Aramid-Fibersheets 1307A can be hand rolled using a Formica roller to force thefirst set of Aramid-Fiber sheets 1307A to ply with the adhesive.

Any number of plies of the first set of Aramid-Fiber sheets 1307A. Forexample, a four ply set of Aramid-Fiber sheets 1307A may, followed by anadditional layer of adhesive, and then followed by a second four ply setof Aramid-Fiber sheets 1307B. Nine plies or more may also be used.

Referring to FIG. 13E, once the last plies of the second set ofAramid-Fiber sheets 1307B are applied, another layer of adhesive isapplied. A first backer board 1309 is then applied to the second set ofAramid-Fiber sheets 1307B. An exemplary embodiment of the backer board1309 could be 5/16″ thick and applied in 8′ wide spans. Installation ofthe backer board 1309 is similar to an installation of bricks in that isadjacent seams are staggered (e.g., bricks are typically laid in astaggered or “stair-step” pattern where the seams or vertical edges ofthe bricks do not overlay). The backer board 1309 is then fastened tothe first panel 1305 using screws and or an adhesive. The backer board1309 should also be fastened with sheet rock screws at about 4″ O.C. onthe seams of the armored panel and at about 6″ O.C. in the center offield of armored panel.

Referring to FIG. 13F, an additional layer of adhesive or double-sticktape is applied. The adhesive may be applied using the ¼″ notchedtrowel. A layer of tiles 1311 is applied to the adhesive. In addition,backer board 1311 is installed with a different stagger than the oneassociated with backer board 1309 to assure no overlap of seams betweenthe two backer boards. In one exemplary embodiment, the layer of tiles1311 is formed from 8″×8″ Dal-Tile Quarry tiles. The individual tilesmay be applied so that they abut one another, with a minimum of space orno space left between the tiles. The tiles are applied starting at thebottom, and the final row of tiles is cut to fit at the top of the layerof tiles 1311.

Referring to FIG. 13G, adhesive is applied to the layer of tiles 1311. Asecond backer board 1313 is then applied to the adhesive. The secondbacker board 1313 may be of similar size and composition to the firstbacker board 1309. Using the ¼″ notched trowel for the adhesive, thesecond backer board 1313 is attached horizontally with no correspondingseams to the layer of tiles 1311.

Referring to FIG. 133H, a second panel 1315 is installed, keeping theleading edge on the exterior. The leading edge of the second panel 1315is screwed to an adjacent panel, such as the second backer board 1313.The screws may be spaced at about 6″ along a vertical extent of theleading edge.

Referring to FIG. 13I, after the second panel 1315 is installed, ahardened steel mesh 1317, such as the AMICO Secure Fence System, can beattached to the second steel panel 1315. The hardened steel mesh 1317will be attached every 12″ to steel studs along the second panel 1315and welded continuously on a 4″ lap joint on both sides of the lap. Thesecond panel 1315 is attached to outside edge of the L channel, usingthe 34 in height, 10 gauge plurality of tracks 1303, by welding thesecond panel 1315 to the edge of the L track previously installed. Thewelds should be 6″ O. C., a minimum of 1″ long, and repeated on all foursides.

Referring to FIG. 13J, weld a ½″ rebar horizontally 1321 starting at thebase and spaced every 16″ up the second panel 1315. Once the rebar 1321is welded, a tack weld of a stucco mesh 1323, such as the AMICO SecuraLath, to the ½″ rebar is made every 6″ across the stucco mesh 1323, asshown in FIG. 13K. Next, as shown in FIG. 13L, an exterior frame 1325 isformed from welding a lip around the edges of the second panel 1315.

In FIG. 13M, a stucco surface 1327 is applied with, for example, 1¼″total thickness of STO High Strength exterior stucco. The manufacturesinstructions are followed to form a finished stucco surface 1327exterior wall. As noted above, other exterior finishes can be applied tothe AMICO Secure Fence system other than stucco. These include brick,stone, etc. Finally, as shown in FIG. 13N, an interior surface, such asa ⅝″ gypsum board or drywall, is attached to the first side of the firstpanel 1305.

Alternatively, once the second panel 1315 is installed, an exteriortrack lip 1315A (not shown) may be welded to the outside of the secondpanel 1315. Welding can be performed at 6″ intervals with a minimum of1″ welds.

An exterior surface 1317 (not shown) can then be attached to the secondpanel 1315 using the exterior track lip 1315A (not shown). The exteriorfinish may be a drywall sheet or gypsum board 1317. Other exteriorfinishes, such as brick, stone, stucco, etc., may also be applied to thesecond panel 1315.
